'O ALL WHM IE MAY CONCERN:

Be it known that We, ELI FLANEGN and A. B. SMITH, of Pittsburg, in the county of Allegheny, and State of Pennsylvania, have invent-ed an improved Pendulum Pump; and We do hereby declare that the following is a. full and exact tiescription thereof", reference being had to the accompanying drawings, making part of this epecitication- Figure 1 "being e top View of our improved pump.

Figure 2, e eide elevation thereof, the position of a well, also, being shown in connection with the same.

Like lettere designate corresponding parts in both figures.

Letter A indicates the pump-frame; B, the spring, or other moving power; C, the clock-Work or gearing; D, a Well; G, the pump-tuloeg H, the regulating pendulum; and l the levez which operates the punip-piston, through the connecting-rod i'. The principal diliiculty in working the pump lies in the balancing of the lever Il, ne the height of the Water x varies in the well. The object of our invention is to oliviate this difficulty. For this purpose we employ a. counter-Weight, L, on the lever, emi so arrange it es to move it out or in,'as the Water lowers or rises in the Well, at jlrst 'the proper rete to constantly counterbalance the varying weight of Water in the pump. To e'ectthie the `weight L is supported on n har, M,'whioh slides on the top of the lever I. There is' a raclg, m, on the under side of this bar, which gears into a pinion, n, cn the shaft oi' a pulley, N. @n this pulley or drame corri, in, is Wound, seid oord extending down into the Well and terminating in a Boating Weight, P. Another'oord,.i, is wound round the pulley N in the opposite direction, ana` has o counter-weight, Q, only sufficient to move the bar M and weight L inward onthe lever l, when the lioating Weight P is raised by the Water; but when water lowers the Weight P is euiiieent to draw up the weight @,'auf also move the bar M nucl weight L out'var, Thus, hy poportioning all the parte right, the oeting weight P Will regulate the position of l'the balance-Weight L se as to adapt the lever l to all veria-tions in the height of water in the well.

What We claim es our invention, and iiesire to secure by Letters Patent, is-

The Heating weight l), counter-weight @pinion-pulley N, moli-bar M, and balance-Weight L, arranged and operating together, substantially as andfor the purpose herein specified.

The above specification of ouin improved penclulum pump signed hy us this day of July, 1866-.

A. B. SMITH.
